Hello Meelis, Perhaps of interest ... i was being hit with the qla2xxx driver panics as well on my v880. I unplugged the second FCAL loop to the backplane, and this fixed it. Perhaps this is something you could try?
I have not tried on my V880 but I got similar trouble on V480. But where is the secondary loop on SB1000/E280R (having the same mainboard)? Hmm, come to think of it, there is a connector marked with double arrow, the back of mainboard but I do not think I have seen any cable that would fit there. -- Meelis Roos
